Ikhwalithi Ephezulu YaseShayina ye-TEG Iyunithi Yezimboni Zokuqeda Uketshezi emzimbeni - I-Natural Gas Sweetening Skid – Rongteng

Isingeniso

I-MDEA ye-natural gas desulphurization (desulfurization) skid, ebizwa nangokuthi i-MDEA sweeting skid kanye neyunithi ye-natural gas desulfurization, iyithuluzi elibalulekile ekuhlanzeni igesi yemvelo noma ukulungisa igesi yemvelo.

Iyunithi ye-MDEA ye-natural gas desulfurization ihlale yamukelwa lapho i-carbon sulphur yegesi ephakelayo iphezulu uma kuqhathaniswa, futhi lapho ukususwa okukhethiwe kwe-H₂I-S iyadingeka ukuze kutholwe igesi ene-asidi efanele ukucutshungulwa kwezitshalo zikaClaus, nezinye izimo ezingakhethwa ukuze kukhishwe i-H₂S; Lapho kususwa u-H₂S kanye nokukhipha inani elikhulu le-CO₂, i-MDEA ingasetshenziswa njengendlela exubile ye-amine;

Njengamanje, ubuchwepheshe obuyinhloko be-desulfurization obusetshenziswa ekukhiqizeni izimboni ekhaya naphesheya yibo: i-desulfurization eyomile (ngokomzimba, i-biological desulfurization kanye ne-desulfurization emanzi.

I-Desulfurization emanzi ihlanganisa indlela yokumunca kanye nendlela ye-oxidation emanzi. Indlela yokumunca amakhemikhali, emelelwa ukumuncwa kwe-amine yotshwala, isetshenziswe kabanzi embonini. IHydrogen sulfide esegesini idluliselwa esigabeni esiwuketshezi ukuze kuhlanzwe igesi.

Ubuchwepheshe be-Desulfurization

Ubuchwepheshe be-biological desulfurization, esimweni somoya-mpilo omncane, bungaguqula i-hydrogen sulfide ibe isibabule esiyisisekelo, kodwa ubuchwepheshe be-biological desulfurization abukavuthwa okwamanje.

Ubuchwepheshe be-dry desulfurization buhlanganisa indlela ye-iron oxide, indlela ye-carbon activated, indlela ye-molecular sieve, indlela yokushintshanisa i-ion, indlela yokuhlukanisa ulwelwesi, indlela ye-biochemical, njll. Okwamanje, ubuchwepheshe be-PSA eyomile busetshenziswa kakhulu ekwelashweni kwe-desulfurization encane yegesi yemvelo embonini, elawulwa ngokugcwele yikhompyutha, ukusebenza okuzenzakalelayo, kanye nokususwa okuzenzakalelayo kombhoshongo wephutha, ukuze kutholakale ukusebenza okuphephile isikhathi eside, ukuze kutholakale ukusebenza okuphephile isikhathi eside.

izindlela ze-desulfurization

I-amorphous iron hydroxide (inqubo eyomile). Izici: inezici zokunemba okuphezulu kwe-desulfurization, umthamo wesulfure ephezulu, amandla amahle nokunganakwa. Isetshenziswa kabanzi ekukhishweni kwe-hydrogen sulfide kugesi yemvelo, igesi yokwenziwa, i-biogas, igesi yamalahle, i-coalbed methane kanye nezinto ezihlukahlukene eziqukethe amakhemikhali sulphur; I-amorphous hydroxyl oxidation desulfurization i-reaction desulfurization, engakwazi ukulawula ukujula kwe-desulfurization. Kuyinqubo ye-desulfurization enhle. Ngokugcwala kwe-desulfurizer kanye nokungena kombhoshongo we-desulfurization, umphumela we-desulfurization uzokwehla kakhulu, futhi okuqukethwe kwe-hydrogen sulfide kugesi yemvelo ehlanzekile kuzokhuphuka kakhulu, ngakho-ke kuyadingeka ukufaka esikhundleni se-desulfurizer ngesikhathi.
